Restore Full Functionality to Your Vehicle’s Electronics
Are you experiencing a cascade of bizarre electrical problems in your Saturn Outlook or other GM vehicle? Flickering lights, malfunctioning power windows, intermittent wipers, or a security system that acts on its own are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can make your vehicle frustrating and unreliable to operate. This isn’t just an inconvenience; it can affect safety systems and your vehicle’s overall performance.
We offer a direct, reliable solution: a replacement Body Control Module, part number 15948438, delivered to your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). By programming the module before shipment with the latest GM software updates, we eliminate the need for an expensive trip to the dealership for coding. This allows for a much simpler installation process, getting you back on the road with confidence.
From the Diagnostic Bay
We had a 2008 Acadia come in with the owner convinced they needed a new power window motor. The driver’s window would work one day and not the next. They’d already replaced the switch to no avail. After a quick scan, we saw communication fault codes with the BCM. Instead of chasing individual components, we checked the BCM’s data stream and found it was intermittently failing to send the ‘window down’ command. A new, programmed BCM fixed not only the window but also a mysterious interior dome light issue the owner had forgotten to mention. It’s a perfect example of how one failing module can create multiple, seemingly unrelated symptoms.
Is Your BCM Failing? Common Symptoms
- ✔ Intermittent or non-functional power windows, locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on).
- ✔ Malfunctioning windshield wipers or washers.
- ✔ False alarms from the security system or issues with the key fob.
- ✔ Warning lights appearing on the dashboard without a clear cause.
- ✔ Problems with the heating and A/C blower motor controls.
- ✔ Radio or infotainment system issues.
The Perfect Solution for Your 2007-2010 Outlook BCM
This module is the definitive fix for these electrical gremlins. We take the guesswork out of the repair. Simply provide your VIN during checkout, and our technicians will flash the module with the correct software and vehicle-specific configuration. This ensures that all the features your vehicle came with from the factory will work correctly with the new BCM. This unit is a direct replacement for a wide range of original part numbers, including 15948438, 25892622, 20815898, and many more, ensuring broad compatibility across numerous GM models.
Installation and Post-Install Procedures
Installation is straightforward for a DIY mechanic with some experience. The BCM is typically located in the center dash or under the steering column. Once the new module is installed, most functions will work immediately. However, in certain vehicles, a couple of additional steps, known as relearn procedures, might be necessary. These are not required for every vehicle but are important to be aware of:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a capable scan tool. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: Some models may require a recalibration of the brake pedal position sensor to ensure proper brake light and traction control operation.
Please consult a factory service manual or a qualified technician for vehicle-specific instructions.
Frequently Asked Questions
Why do you need my vehicle’s VIN?
Your VIN is essential because it allows us to program the Body Control Module with the exact software and settings for your vehicle’s specific options and features. This ensures a seamless installation and proper function of all electronic components, avoiding a costly trip to the dealer.
Is this BCM difficult to install?
For someone with moderate mechanical skill, the physical installation is typically not difficult. The module is usually located behind the dash and requires removing a few panels for access. Since we pre-program the unit, the most complex part of the job is already done. However, some vehicles may require post-install procedures like an airbag sync, which needs a professional scan tool.
Will this fix my specific electrical problem?
This module is the solution for issues directly caused by a failing BCM. If you are experiencing several of the symptoms listed, such as erratic lights, lock, and window behavior, it is highly likely that the BCM is the culprit. Proper diagnosis is always recommended to confirm the BCM is the point of failure.
What happens if the airbag light comes on after I install it?
This is a known possibility on some GM vehicles. It means the new BCM needs to be electronically ‘introduced’ to the airbag module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed by a shop with a high-level diagnostic scan tool to sync the components and turn off the light.
Is there a core charge for my old part?
No, there is no core charge for this part. You can keep your original module without needing to send it back to us.
